我有两个JSpinner组件，我为它们创建了一个自定义异常，并且运行良好。昨天我在 Netbeans 中修改了微调器，我添加了一个微调器模型编辑器，因为我只想要正数。

所以现在我只有正数，但是当我输入 -1 之类的东西时，它不会像以前那样显示错误消息，为什么？

这是我的代码：

   public int getAlerte() {
        int res = 0;

        if (Integer.parseInt(jSpinnerTime.getValue().toString()) <= 0 ||
            Integer.parseInt(jSpinnerTime.getValue().toString()) >1000) {
            JOptionPane.showMessageDialog(this, "Time should be between 1 and 1000",
                    "Alert", JOptionPane.ERROR_MESSAGE);
            res = 1;
        }       
        if (res == 0){
            int visperiod = Integer.parseInt(jSpinnerTime.getValue().toString())/2;            
            if (Integer.parseInt(jSpinnerFreqV.getValue().toString()) <= 0 ||
                Integer.parseInt(jSpinnerFreqV.getValue().toString()) > visperiod){
                JOptionPane.showMessageDialog(this, "Visualization frequency should be between 1 and "+visperiod,
                    "Alert", JOptionPane.ERROR_MESSAGE);
            res = 1;
            }

        }
        return res;
    }

我尝试了 SSCCE，希望它对您有用，代码如下：

import javax.swing.DefaultListModel;
import javax.swing.JOptionPane;


public class JPanelPoly extends LayerPanel{

    private RendererContainer rc = new RendererContainer();
    private ParametersTable parametersTable= new ParametersTable("TYPE");
    private int nbrParameter; 
    private int nbrCenter; 
    private Frame parent;


    public JPanelPolyg() {
    initComponents();
        jListParameter.setModel(rc.getModel());
    jListParameter.setCellRenderer(new SimpleRenderer());
    jSpinnerEnters.setValue(150);

    }

    public JPanelPoly(Frame parent,int nbrCenter, int nbrParameter){
    initComponents();
    this.nbrCenter = nbrCenter;
    this.nbrParameter = nbrParameter;
    jListParameter.setModel(rc.getModel());
    jListParameter.setCellRenderer(new SimpleRenderer());
    jSpinnerEnters.setValue(150);
    this.parent = parent;


    }



    public RendererContainer getListParameterModel(){
    return rc;
    }
    public int getNbrCenter(){
    return (Integer)jSpinnerEnters.getValue();
    }

    public int getNbrParameters(){
    return (Integer)jSpinnerParameter.getValue();
    }

问题是：当我输入 -1 或单击“确定”而不在 jSpinner 中输入任何内容时，它永远不会显示错误消息。
